Red states and blue states may like to point to one another as the source of all that is wrong with the U.S., but the truth is that each of the 50 states has its own virtues and vices. For example, Missouri has the worst drug use problem. And it certainly comes as no surprise that Nevada is the most gambling-addicted.But the cost of state sins is something we have to share as a nation. Gambling alone costs the U.S. about $5 billion per year. That’s nothing compared to the amount of money we lose from smoking, though – over $300 billion per year. Harmful behavior on the individual level can add up to staggering economic costs on a national scale.Some states are more well-behaved than others.
